Milla Jovovich launches Mempalace AI memory tool
Actress Milla Jovovich and Libre-Labs CEO/software developer Ben Sigman have published Mempalace, an open-source tool designed to give LLM-based chatbots persistent memory across conversations. Inspired by the ancient loci or "memory palace" method, Mempalace maps user information to mnemonic structures and stores that data locally on users' devices rather than sending it to cloud model providers. The project is available on GitHub; Sigman reported it received over 10,000 stars and 50 pull requests within 24 hours. Computer scientist Sean Ren of Sahara AI noted that formal benchmark tests are still needed to verify how much Mempalace actually improves chatbot recall. The tool emphasizes local storage as a potential means to reduce cloud resource use and privacy exposure.
Open-source technical release proposing local on-device memory for LLM chatbots could affect conversational UX and privacy practices; notable GitHub uptake but no independent benchmarks yet, so limited immediate industry impact.

Milla Jovovich launches Mempalace to boost chatbot memory
Actress Milla Jovovich and Libre-Labs CEO/developer Ben Sigman released Mempalace, an open-source tool intended to improve how LLM-based chatbots retain and re-use information across conversations. The tool's design is inspired by the ancient Loci or “memory palace” learning method and aims to store user data locally on devices rather than in AI-provider clouds, which the creators say could save resources and costs. Mempalace is available on GitHub; Sigman reported it received over 10,000 stars and about 50 pull requests within 24 hours. Independent benchmarking of whether Mempalace measurably improves chatbot memory remains outstanding, according to computer scientist Sean Ren of Sahara AI.
MemPalace: Open-source Local AI Memory System
MemPalace is an open-source, local-first AI memory system launched April 5, 2026. Co-founded by actress Milla Jovovich and crypto CEO Ben Sigman, the project reached ~48.5k GitHub stars shortly after release. MemPalace provides cross-session persistent memory for AI assistants using a spatial “palace” hierarchy (Wing/Room/Hall/Drawer), a 4-layer progressive loading strategy that boots with ~50–170 tokens, and a zero-LLM write path that stores data locally (ChromaDB) without calling LLM APIs. It implements a temporal knowledge graph in SQLite to avoid stale facts and exposes 29 MCP tools for integration with Claude Code and other MCP clients. The project introduced an AAAK compression format (claimed 30× compression) and faced independent critiques over benchmark methodology, compression trade-offs, and some unimplemented features.
MemBot AI: Customer Support Assistant with Persistent Memory
MemBot AI is a memory-enabled customer support assistant described in a developer post by Lavkush Yadav (published 2026-06-06). The system stores and retrieves customer issues, preferences, and conversation history to produce context-aware responses and reduce repetitive explanations. Its architecture includes a user interface (built with Streamlit), a language model layer, a memory engine, and persistent storage. Core features highlighted are persistent memory tied to customer identifiers, a memory timeline for reviewing history, preference retention, and an interactive dashboard. The author lists the technical stack (Python, Streamlit, Groq API, JSON-based storage, GitHub) and suggests future improvements such as vector databases, semantic memory retrieval, sentiment analysis, and multi-agent workflows.
